recalc.modelStruct {nlme} | R Documentation

## Recalculate for a modelStruct Object

### Description

This method function recalculates the condensed linear model object using each element of `object` sequentially from last to first.

### Usage

    ## S3 method for class 'modelStruct':
    recalc(object, conLin, ...)

### Arguments

`object` | an object inheriting from class `modelStruct`, representing a list of model components, such as `corStruct` and `varFunc` objects.
`conLin` | an optional condensed linear model object, consisting of a list with components `"Xy"`, corresponding to a regression matrix (`X`) combined with a response vector (`y`), and `"logLik"`, corresponding to the log-likelihood of the underlying model. Defaults to `attr(object, "conLin")`.
`...` | some methods for this generic require additional arguments. None are used in this method.

### Value

the recalculated condensed linear model object.

### Note

This method function is generally only used inside model fitting functions, such as `lme` and `gls`, that allow model components, such as correlated error terms and variance functions.
